A new phaeodarian species, characterized by the presence of long developed side branches recurved proximally and distally on the surface of its radial tube, was described as Auloscena pleuroclada. This new species was only collected from the layers below the 250 m depth in the Sea of Japan. They have never been found in the shallower layers (above 250 m) of this sea or in other investigated areas. The distribution of the present new species is presumably restricted within the deep water of this area, and this species could be a specific phaeodarian adapted to the deep-sea environment.

Haeckel's 'art book', Kunstformen der Natur, is likely familiar to most protistologists as it is probably Haeckel's best known work, and it prominently featured protists. No doubt many of us have used some of the images from it in our lectures. Most familiar are perhaps the often-reproduced images of nassularian radiolaria, but plates were also devoted to phaeodarians, acantharia, foraminifera, ciliates, diatoms, dinoflagellates and desmids.

DNA metabarcoding on a single organism is a promising approach to clarify the biological interactions (e.g., predator-prey relationships and symbiosis, including parasitism) of difficult-to-culture protists.

Siliceous planktonic species of the phyla Retaria and Cercozoa were investigated from the surface to a 200 m depth around the eastern Indian Ocean (80.00°-96.10° E, 10.

A phaeodarian morphotype, characterized by the feet surrounded with forked pedal spines with anchor-like structures, was collected in the subtropical North Pacific. Considering the morphological and phylogenetic uniqueness, this morphotype is described as Gazelletta kashiwaensis sp. nov.
